Use the information from the graph to answer the question.

A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 12, velocity in meters per second on the y axis, numbered 0 to 45. A line starts at (0, 40) and ends at (12, 10).

What is the acceleration of the object?

__ m/s2

wvbbvvv

power out to power in less than 100%

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is
